As a result we had to buy additional airline tickets to catch up with the sailboat at Antigua. The airline paid us "denied boarding compensation," but they refused to reimburse our additional air fare or the value of the two days on the cruise we lost.

I laughed. The DOT seems to contemplate OP's right to recover additional air fare when denied boarding by airline. Even if the reasons for the IDB are not identical.
